Authorities believe they have found the remains of the last victim of the Arizona flash flood tragedy. According to CBSNews, the remains found Wednesday may belong to missing 27-year-old Hector Miguel Garnica. He would be the 10th victim to perish in the flash flood.

Gila County Sheriff's officials said that the official identification of the body is dependent on DNA analysis. However, they do believe that the body does belong to Garnica and have notified his family.

Last weekend, the extended Garnica family was swimming along the river at the Tonto National Forest. A flash flood came upon them and killed nine, including Garnica's wife and three children (pictured above).

First responders called the flash flood a "40-foot-wide black wave" moving at 45 miles per hour. "All of a sudden, this wall of water, and rock and debris, just came rushing at them," a witness said of the incident.

Four of the 14 family members were rescued. They were all from Phoenix.
